dashes in cabal package names

[Isaac Jones]

Does anyone have any objection to allowing dashes within Cabal pacakge
names?  This might impact the parser for HC-PKG, but that's the way it
is now, and seems to make the most sense.

I think the only change to HC-PKG would be to use a non-dash separator
between the package and version; we can decide exactly how to do that
at a later time.


peace,
